PERM uTATloN-LOCK FOR BAGS.

SPECIFICATION forming part of Letters` Patent No. 243,149, dated June `21, 1881.

Application filed December 2, 1880. (Model.) Patented in Germany April 14, 1880.

To all lwhom it may concern:

Be it known that I, MosEs MERZBACH, of Berlin, Prussia, German Empire, have invented a new and useful Improvement in Permutation-Locks, (patented in Germany on the 14th of April, 1880, No. l1,435,) which is fully set forth and described in the following specication.

My invention relates to permutation ortype locks for trunks, albums, boxes, frames of traveling-bags, ladies bags, or similar receptacles.

My invention consists in the general arrangement andin the construction of details, as illustrated by the accompanying drawings, in which- Figure lis a front view of a type-lock applied to the frame of a bag; Fig. 2, a plan, and Fig. 3 an end View, of the same. Fig. 4 is a crosssection of lock and frame, and Fig. 5 a plan of the closed frame without the lock. Fig. 6 is a longitudinal section of the closed lock in a larger scale; and Figs. 7, 8, and 9 are detail views, showing the construction of the lock.l

It will be seen that the lock is placed parallel with the frame M, and entirely on one-half of the latter, while the other half of the frame carries only the locking-hook A. As the lock is arranged parallel with the frame, the number of its permutation or type rollers is made independent of the width ot' the frame, and by the construction of details hereinafter dcscribed an easy opening andl closing of the lock is attained.

A particularity of this permutation-lock is that the key c need not be removed from the lock, as is the case in ordinary permutationlocks, but remains always in it. A further peculiarity of this lock is that the key c does not directly close or open, but indirectly by acting on a tumbler, b, placed under the key in the box B and moving parallel with the key,

which arrangement constitutes the principal 'which are marked with types.

to themselves, but pressed at their lower side by the plates eat the end ofthe springsf. By this compression the prismatic rollers tend to place themselves with one side against the top plate, e, of the springs f, whereby an easy and accurate adjustment of the rollers is obtained. When turning the rollers a. slight pressure is suflicient to overcome and press down the springs f.

It is evident that instead of spiral springs, as shown, other suitable and known spring devices may be applied.

The lock-box B is fastened upon the frame M of the bag, and carries two projecting plates or brackets, a, supporting between them the immovable axle or socket a', provided with a longitudinal slot. The slot is placed at the lower side of the axle, or in the direction of the lock-box B. On this axle are mounted the permutation-rollers, which may be moved independently of each other, and the dat sides of These rollers are made hollow and provided with covers p', shaped as shown by Fig. 9. If all the rollers are placed with their slots pfdownp'ard, then the lock may be opened by the key c. The latter is movable in the axle or socket x, and is always pressed outward by a spring, o. It is connected with the tumbler bby a pin, c', and has projections d, which are inclosed in the hollow rollers without preventing the turning of the latter. As long as theslots p of the rollers are not directed downward, every axial movement ot' the key c is prevented and the lock is closed; but if the slots are directed downward, the key may be pressed inward, thereby pushing back the tumbler b and opening the lock.

lt is evident that, instead of applying the spring o direct to the key c, the spring-action may be applied indirectly-for instance, by causing a spring to act on the tumbler I).

Although the opening of the lock can only be ef'ected in a given position, the frames can be closed in every position of the permutationrollers, because the hook A will press back the tumbler b sufticiently to fall in behind the nose q of the latter, the connection between the key and the tumbler by means of the pin e' being sufficiently elastic to permit a small displacement of the tumbler against the key.

For boxes, trunks, albums, and for similar IOO receptacles the construction ot' the lock is substantially the same, only the form ot' the lockboX must be adapted to the receptacles.

What I claim is- 1. In permutation or type locks for the purposes described, the combination ot type-rollers p p, placed with their axis parallel to the frame to which the lock is applied, with a lockbox, B, attached to one halt' of the said frame, a hook, A, attached to the other half, a key, c, movable in the axis of the type-rollers, and a tumbler, Z1, actuated by said key, substantially as described.

2. The combination ofbrackets a with hollow axle x, permutation-rollersp, plates e, provided 1 5 with spring-action, key c, and tumbler b, provided With pin e', constructed and operating substantially as described.

In testimony whereof I signed this specication in the presence of two subscribing Witnesses.
